Struct Texture 

pub struct Texture { /* private fields */ }

The Texture struct provides deterministic CPU texels for shader sampling, image access, and atomic assertions.

Implementations

impl Texture

pub fn new(width: u32, height: u32) -> Result<Self, VmError>

pub fn new_3d(width: u32, height: u32, depth: u32) -> Result<Self, VmError>

Creates a CPU texture with three-dimensional addressing for VM texture tests.

pub fn write(&mut self, coord: [u32; 2], value: [f32; 4]) -> Result<(), VmError>

pub fn write_3d( &mut self, coord: [u32; 3], value: [f32; 4], ) -> Result<(), VmError>

Writes one texel in a three-dimensional CPU texture.

pub fn write_u32(&mut self, coord: [u32; 2], value: u32) -> Result<(), VmError>

Writes one unsigned integer texel for integer image and atomic tests.

pub fn fetch(&self, coord: [u32; 2]) -> Result<Value, VmError>

Fetches one texel without interpolation.

pub fn fetch_u32(&self, coord: [u32; 2]) -> Result<Value, VmError>

Fetches one unsigned integer texel without interpolation.

pub fn sample(&self, uv: [f32; 2]) -> Result<Value, VmError>

Samples one texel using bilinear interpolation in normalized UV space.

pub fn sample_3d(&self, uvw: [f32; 3]) -> Result<Value, VmError>

Samples a three-dimensional texture using trilinear interpolation.
